One Chicago-area father got a big, wonderful surprise over the weekend.
During a holiday concert at the Copernicus Center in Chicago, Cpl. Zack Mucha -- home for his first Christmas in at least two years -- surprised his unsuspecting father by walking on stage while "I'll Be Home For Christmas" was played by an orchestra.
WGN reports the heartwarming reunion was arranged by Anthony Kawalkowski, the musician hosting the show, in partnership with the Hillcrest Nursing Center in Round Lake, where Zack is from.
